I tried to install igraph for mac (the C package) but I'm unable to find the library.
bobs-imac:connectivity roberto$ gcc igraph_test.c -I/usr/local/igraph -L/usr/local/lib -ligraph -o igraph_test
igraph_test.c:1:20: error: igraph.h: No such file or directory

igraph_test.c:5: error: for each function it appears in.)

bobs-imac:connectivity roberto$ pkg-config --libs --cflags igraph
Package igraph was not found in the pkg-config search path.
Perhaps you should add the directory containing `igraph.pc'
to the PKG_CONFIG_PATH environment variable
No package 'igraph' found
bobs-imac:connectivity roberto$ pkg-config --libs --cflags igraph.pc
Failed to open 'igraph.pc': No such file or directory
No package 'igraph.pc' found
Does anybody know how to fix it?
Thanks,
Bob
